Hello, As you can see in the attached QUCS schematic, I am trying to do an AC simulation of a simple BJT circuit while sweeping a resistance in the circuit. I would like to plot V_e.v versus the resistance, but the indep variable (x-axis) that is used by default in plots is acfrequency, with no apparent means to change it besides editing the .dat file produced by the simulation. I only have one frequency that I'm simulating at... can that simplify the problem at all? If I edit the generated .dat file to change (for example) <dep Pr1.i acfrequency R_load> to <dep Pr1.i R_load>, then R_load is the x-axis as I want it, but I'm hoping there's a way to make this happen automatically. Any suggestions? Thanks! Patrick jpb...@gm... |

Thanks! There are 2 possibilities for it: Please see attached modified schematic. Hope this helps, Stefan. |
